Paz Morillo

Associate professor at UPC
Research area: Discrete Mathematics

PhD in Computer Science obtained at UPC (1987)


I received the degree in Mathematics from the Universitat de Barcelona in 1983 and the PhD in Computer Science in 1987 from the Universitat Politècnica de Catalunya. In september 1987 I joined the Department of Applied Mathematicsat UPC. Since 1992, my research interests are mainly related to cryptography, I have been the advisor of 6 PhD thesis onthe subject of mathematics applied to cryptography and currently I’m supervising 3 other thesis on electronic voting, one of them to be presented in February 2016.
